Preservation Intent - Maps

NLA Digital collections: Statement of Preservation Intent

Collection Area: Maps

The Library's digital Maps collection includes born digital images from internal and external sources. As a largely published collection, Maps should consider the Preservation Intent of related institutions in determining intention to preserve.

Maps intend that:

All Maps digital preservation masters should be retained in perpetuity, including all metadata. All technical properties should be maintained to the full extent possible.

Derivative copies created for access should be maintained only for as long as useful; a new derivative version may be generated according to future access requirements.

Born digital maps and map related material coming from external and internal sources should be treated similarly.

Other Issues:

May include some material 'belonging' to other collection areas (e.g. Manuscripts) who need to be consulted.

May include 'marginalia' and other textual data.

Although Maps specify digital formats acceptable for acquisition through the CDP, this may change over time, requiring revision of preservation intent profile.

Digitised items may be re-captured over time.

Digital items come into the maps collection via three main collecting streams:

Digitised internally through DCM;

Digititised from an external source;

Born digital, created from an external source; and

A combinination of the later two catagories delivered via a carrier (physical, such as CD, DVD or logical, such as email). This content may or may not require different preservation actions.

Some Image files which contain metadata may need to be modified/edited overtime. Alternatively, the metadata might have to be removed from the file and stored separately.

There may be some material which is the responsibility of another agency to preserve.
